I have downloaded video files from my Sony DSC-T30 digital camera to my hard drive. I have opened the files and placed them on the timeline using Vegas Explorer. They are MOV.MPG files. Having edited the project I have found that some of the events turn red and it is impossible to render and complete the project. I have tried cutting the time down to 15 minutes and splitting the project in two but that doesn't work either. Sometimes the error message relates to low memory sometimes to files that cannot be found and sometimes it states that the device is in use. Very confusing. I am running a new Alienware computer with all the bells and whistles. Seems to work fine with avi files. Could it be a MOV.MPG issue. Any ideas?
